Under Dohmke’s leadership, GitHub advanced its mission as part of Microsoft’s CoreAI organization, delivering major achievements across accessibility, security, and developer tools. GitHub Actions matured into the world’s leading continuous integration platform, now powering 3 billion minutes per month, a 64 percent year-over-year increase. GitHub Advanced Security redefined industry standards, leveraging AI to reduce remediation times by 60 percent and enabling teams to fix vulnerabilities three times faster.

Dohmke also oversaw the launch and scaling of GitHub Copilot from an early autocompletion tool into a comprehensive AI-powered development platform, incorporating conversational coding, code review, bug fixing, and full-stack app creation through GitHub Spark. Today, GitHub Copilot serves over 20 million users and stands as a leader in the rapidly growing AI development market. In the past year, it became Microsoft’s first multi-model AI solution, integrating capabilities from Anthropic, Google, and OpenAI.

During his tenure, Dohmke expanded GitHub’s reach to the European Union, Australia, and the U.S. federal market through FedRAMP certification. He also championed the company’s commitment to open-source development, noting the doubling of AI-related projects in the past year alone.

“Thomas has been an extraordinary leader, guiding GitHub into a new era of AI-driven software development,” said a Microsoft spokesperson. “His vision and execution have positioned GitHub as the most widely adopted AI developer platform in the world.”

Dohmke expressed deep pride in the company’s accomplishments, stating, “GitHub has never been stronger than it is today. We have empowered millions of developers worldwide and launched a new age of AI-assisted software creation. I am confident the team will continue to shape the future of development for years to come.”

Dohmke will remain in his role through the end of 2025 to ensure a smooth transition. GitHub will announce succession plans in the coming months.
